could someone help me out here

the numbers on the picture of the main relay show as


7 8

5 6

3

1 2

but the schematic of the main relay (bottom diagram) shows the numbers in a totally different order...

so how do i wire the main relay? according to which diagram???

 

You have to use both...based on the numeral given.
Take it one wire at a time,

Use the lower chart to determine what each wire connects to
----------------------------------------------------------------------------------
Use the upper chart to determine the actual locations of the terminals
at the relay..

 

what is number 6? is it for the starter?

 

That is what is called the "starter signal"..

What it does is energize the fuel pump and injectors
for two seconds to prime the fuel system before attempting to start..

The starter motor itself is on it's own separate circuit..

The main relay supplies power to
fuel pump,ECU,and injectors..
